In 2025, 111,014 Audi TT cars had a regular MOT in Great Britain. 77% passed first time, compared with 67% for all cars of the same ages, which makes the TT better than average. Adjusted for age, it ranks 14 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 3 years old, 92% of TTs passed first time (all cars that age: 88%). By 20 years, that figure is 61% (all cars: 58%). It beats the average car at every age with enough data, from 3 to 20 years.

What fails most on a Audi TT
The area that lets the TT down most, relative to other cars, is seat belts and airbags: 1.2% of tests failed on it, 3.7 times the rate for the average car. It does comparatively well on visibility and body and structure.

The six most common failure items
| Failure item | Area | Share of tests |
|---|---|---|
| Tyre tread depth not in accordance with the requirements | Tyres | 3.6% |
| The aim of a headlamp is not within limits laid down in the requirements | Lights and electrics | 3.4% |
| A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning | Lights and electrics | 2.8% |
| A suspension joint dust cover missing or no longer prevents the ingress of dirt etc | Suspension | 2.7% |
| A tyre seriously damaged | Tyres | 2.7% |
| A spring or spring component fractured or seriously weakened | Suspension | 2.7% |
What to check when buying a used TT
Based on where the TT fails more often than other cars, these are the checks worth making before you buy:
- Seat belts and airbags: Pull every belt out fully and let it retract, check the buckles latch, and make sure the airbag light goes out after starting. More
- Emissions and leaks: Look for oil and coolant leaks underneath, listen for exhaust blows on a cold start, and watch for smoke when revving. Repair guide
- Tyres: Check tread across the whole width (uneven wear hints at alignment or suspension faults), and look for cuts, bulges and mismatched brands. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
